The gaming mechanism of this game is intelligent and entertaining and some (most) of the levels are pretty challenging.
I spent several hours finishing the game and I had fun.

But that's quite all for the PROs of the game.
Now for the CONs.
The most serious drawback for the game is the characters movement speed. Optimal speed setting of your ZX Spectrum emulator for this game is somewhere about 300%-400% of the original Spectrum speed. This distorts the music and sounds, so you need to turn those off, but no serious harm, because they're nothing special anyway. Changing characters movement from (very slow) walk to jumps or very quick steps would significantly improve gameplay.
Also, at the end of the game, after finishing all the levels, some of which were kind of tricky, I would expect something more than just the word "congratulations". At least "Thanks to you, Oddi has successfullly escaped the castle" (and saved the princess/killed the evil wizard/sold the stolen treasure/lived happily ever after) would be nice.
